A certain flight arrives on-time 86% of the time. Suppose 181 flights are randomly selected. Use the normal approximation to binomial to approximate the probability that exactly 159 flights are on time. Al least 159 flights are on time. fewer than 149  flights are on time. Between 149 and 169, inclusive are on time.
